This 1893 first edition has the attribution to C.W. Grimm as the inventor on the label, as well as a $1.00 price. The dominoes themselves are wooden, and the notes appear to be a thin veneer that is both glued and fastened by a small metal stud in the center of each domino.
The original game used only musical notations (symbols for notes and rests of durations from a whole note to 1/16). Matches were allowed between any dominoes representing an equal time (i.e. a 1/4 rest could be placed beside a tile with two sixteenth notes and an eighth). No key letters were used as in the later Bramhall version.
